The PCIA says when a disease has advanced to the terminal phase and a patient is unlikely to survive six months, doctors must offer to inform them of this, and advise them of available treatments aiming to bring comfort, not vanquish disease. At this point the disease is beyond reasonable hope of vanquish, and the symptoms may escalate to the point of intolerance. Patients have a right to know when disease-specific treatments offer only a miniscule chance of prolonging their lives for a few weeks or months. And they have a right to know palliative therapies could make them feel a lot better for the time remaining.

Before the PCIA became New York law, they had no such right. I'd like to explore what this means for patient care and decision-making, with a concrete example. I hope to reveal how stunning a reform we might expect.

In November 2010 Frontline aired a documentary called Facing Death. Filmed in the bone marrow transplant unit at Mount Sinai Hospital in Manhattan, it shows intimate scenes of distress, confusion and grief. It reveals chilling examples of physicians following an imperative to attack disease, however miniscule the likelihood of success and irrespective of associated suffering. It exposes aggressive treatments as life-threatening in themselves, and shocking acceptance of individual suffering as necessary collateral damage in medicine's larger war on cancer.

One episode remains seared in my mind. When I saw it, I thought, "This must change."

The patient's name was Norman, and he was dying from complications of his transplant, as 25-30% of patients do. Kyimar, his life partner, was constantly at his side, and her distress was palpable. She approached Karen, his doctor, to relay Norman's request that aggressive treatment be stopped. Karen went to the bedside to clarify the situation. The following conversation ensued:

Karen, leaning over Norman: "What's happening?"
Norman: weakly, barely audible, "I'm scared."
Karen: "If you ever need a ventilator -- you want to tell me something about that?"
Norman: no response"If something happens and you have trouble breathing, do you want to be put on a respirator to help you breathe?"
Norman nods weakly.
Karen: "You do? Is that a yes?"
Another weak nod."Alright. OK." Karen goes on: "If you're tired and you don't want us to do this anymore, that's OK with me. But ya gotta let me know. I don't want to put you through procedures that you don't want to go through. But I don't want to not do the things that are right in terms of trying to help you get better."

Kyimar, who has been at Norman's bedside 24 hours a day for two months tries to protest that Norman is consistent in his desire to sign a "Do Not Resuscitate" order. Karen tells her he's probably ambivalent.

What happened here? The physician apparently believes she obtained informed consent for cardio-pulmonary resuscitation efforts, intubation maintenance and indefinite ventilator support. But it seems to me Norman's consent was uninformed and coerced. Would a frightened, dying person ever reject the only assistance his doctor offers if gasping breathlessness were to seize him? Didn't Karen tell Norman a ventilator was the only "right" course?

When Norman subsequently deteriorates,he's moved to the ICU. After two days, his sister Phyllis, asks "Is my brother dying?" and confronts the inevitable. Phyllis receives sidelong glances and the question turned back at her. "What do you think, Phyllis?" Norman spends four days in intensive care before he dies.

Today the PCIA is in place and a dying patient's consent to treatment must be truly informed. Karen would now be obligated to offer to share with Norman the same information she shares with her colleagues -- she has never seen anyone in his condition survive. Norman is dying. When she talks with him about alternatives to aggressive resuscitative techniques, today she must also reveal that palliative treatment can ease his anxiety, breathlessness and pain if his condition worsens. He need not be scared that choosing to stop treatment would bring even more suffering than he currently endures. She must tell him he could leave the hospital and die at home with hospice care, or move to a palliative unit in the hospital. Doctors must now communicate that palliative support would be just as "right" for Norman as passing a tube into his lungs and adding procedures and machines in the intensive care unit.

If the PCIA diminishes the end-of-life agony of even one patient like Norman, it would be worth the effort of passage. But my guess is, empowered with concrete knowledge of their prognosis and palliative alternatives to invasive treatment, thousands of New Yorkers each year will opt for gentle, peaceful dying. And what a stunning improvement that will be!
